I am trying to make my Smart Array P840 Controller, to be passed through to a truenas VM installation. Its a DL380 Gen9 I have looked at: https://pve.proxmox.com/wiki/PCI_Passthrough https://forum.proxmox.com/threads/pci-passthrough-problems.65485/page-2
which led me to: https://community.hpe.com/t5/prolia...d-memory-features-on-microserver/td-p/7105623
it just wont budge...
Header Proxmox Virtual Environment 8.2.7 Virtual Machine 100 (truenas) on node 'pve' No Tags Logs () kvm: -device vfio-pci,host=0000:08:00.0,id=hostpci0,bus=pci.0,addr=0x10: vfio 0000:08:00.0: failed to setup container for group 59: Failed to set group container: Invalid argument TASK ERROR: start failed: QEMU exited with code 1
what am I missing ?

with no avail, creating a truenas VM with UEFI
A Nvidia gpu I’m able to passthrough with no issue
 
Were you about to utilize the 12ff back plane still? Also is the 90 degree fitting necessary?

I can use all 12 yes and could even use more
90 degree not necessary, depends where you plug the lsi in

Perfect, i want to use the 2sff on the back plugged into the onboard SATA for boot, and this for my storage array. I only have the 840 as a pci so I’ll remove that and put this in place, i dont think i need the 90. What do you use for boot?
 
Oh one more thing
60cm is good enough for two cables, the last one is further away so need like 90cm to make it work
